MEANS FOR COLD-PRESSING CLOTH.

Specification of Letters Patent.

Patented May 5, 1914.

Application filed December 30,1910. Serial No. 600,056.

orcester, in the county of WVorcester and State of Massachusetts, haveinvented certain new and useful Improvements in Means for Cold-PressingCloth, of which the following is a specification.

My invention relates to means for successfully cold-pressing cloth inarotary press, which will enable even an inexperienced finisher to do itsafely, and without getting into trouble, or spoiling the goods beingtreated.

Attempts made by me with rotary presses (such, for instance, as patentedon August 6th, 1878, numbered 206,718) to cold-press cloth by feedingcold water through the second bed, and steam only through the cylinderand the first bed, resulted in failure because the heat from the hotcylinder and that contained in the cloth would, when the cloth reachedthe second or cold bed, cause water of condensation to form upon thesecond bed to such an extent, and so fast, that after a few yards werepassed through the machine, the material would commence to pucker andstick, and then refuse to pass out, becoming eventually torn andcompletely ruined. Similar results were had, though not quite as bad,when cold water was put into the cylinder, and steam only in the twobeds. With a very light pressing merely, the cloth would pass throughthe machine safely, but water of condensation would form so fast and insuch quantity upon the cold surface of the cylinder as to spot the clothand blotch it. So this, too, was given up as impractical.

I now have devised means to COldTPl'GSS a piece of cloth successfully bymaking provision for removing the water of condensation forming upon theface of the cold, or chilled, pressing-member when in close proximity toa hot pressing-member, by taking care of it as fast as it forms thereon,and I do not moisten the cloth to such an extent as to cause it to stickduring its passage through the machine, or to watenspot and becomeblotchy, and thereby unsalable. And I can do this while at the same timeadministering to the goods a very substantial pressing, instead ofescaping disaster only by resorting simply to the lightest kind ofpressing, which was the best we were heretofore able to accomplishbecause of failure to solve the most essential question: how to dispensewith the water'of condensation inevitably forming very rapidly upon thecold pressing member, when opposed by a hot pressing member.

The invention consists in the improvements to be fully describedhereinafter and the novelty of which will be particularly pointed outand-distinctly claimed.

I I have fully and clearly illustrated my in-' vention in theaccompanying drawings to be taken as a part of this specification andwherein Figure 1 represents an end view of so much of a rotary press asis needed to show the application of my invention to such a machine;Fig. 2 showing the opposite end view thereof. Fig. 3 is a top View ofthe parts required to carry out my invention; and Fig. 4 is a frontviewthereof. Fig. 5 is a longitudinal section through the moistureremovingroll. Figs. 6 and 7 show means for bringing the roll shown in Fig. 5into or out of contact with the cold-pressing cylinder of a rotarypress. Fig. 8 shows the relation of certain details to each other. Figs.9 and 10 show another detail in two different positions necessary forproperly handling the cloth.

Referring to the drawings by characters of reference, A is thecold-pressing cylinder of a rotary press, carrying next to its drivinggear a between it and the frame B, another gear which drives not onlythe apron-draft-roll A, by meshing with the gear 0, upon it, but alsothe gear (Z keyed to one end of an arbor e, that has fastened to itsopposite end another gear f. The arbor e revolves freely in a bracket 9fastened on to top of frame, B, and the swing-arm h is strapped looselyto the bracket 9 by the caps i. Upon the opposite end of the machinethere is fastened upon the top of frameB a bracket g upon which swingsthe arm it held upon it by the caps c". In the free ends of theswing-arms h and h is mounted to rotate a cylinder C, held down by thecaps 71: and 7: and between one end of the cylinder C and the swing-armh it has fastened to it a gear Z meshing with the gear f, which is fastupon the inside end of arbor 6, so

that, when the cold-cylinder A of the press revolves in the direction ofthe main driving gear a the cylinder C will turn in the same direction,as indicated by the arrows, and its surface will wipe that of thecold-cylinder A.

B is a hot pressing member preferably in the form of a bed, andcoiiperating with a portion of the periphery of the cylinder A throughan area of the latter preferably to one side of the axis of rotationthereof, said bed being heated by any suitable and well known means, as,for example, steam admitted to the interior thereof. It will be notedthat the cylinder C contacts the cyl inder A on the opposite side of theaxis of the latter from the bed B.

Referring to Fig. 5, it will be seen that the cylinder C has perforated.walls, thicker at one end than at the other, so that its in teriorflares toward the head-end G which is provided with the head C that isof larger diameter than the opening at C of the cylinder C, in orderthat any water in the in terior of this cylinder can gravitate towardand run into the head 0. The opposite end of the cylinder G is closed bythe gear I which forms also the head C While the j our nal P, being madein one piece with head C and gear Z, is sealed by plug P screwed intothe end of the journal P.

Reaching into the head 0 is a station ary suction pipe D with its bent,or lowermost end D reaching to a level somewhat below that of theopening C in the cylinder C, so that any water that may get into thehead C will touch the mouth end D of the pipe D, before it can reach ashigh as the lowermost edge of the opening C A bracket E juts out fromthe swing-arm h to hold the U-piece, or pipe G flanged at H to thesuction pipe D, and held down fast by the clamp or cap F which is boltedto the bracket E,

J is a union which connects the U-piece G with the screw threaded end ofthe elbowpiece K, the opposite or smooth end of which is being held inthe bracket g which forms an arbor for the swing-arm h, with its caps 2"attached to it, to swing upon (see Fig. 8). A vertical pipe L attachedto the elbow-piece K is connected at its other end to a suction pump,not shown in the drawings, for removing not only what moisture mightcollect in the head C, but to create a vacuum in the interior of thecylinder C, which has its outer surface clothed with several layers ofabsorbent cotton cloth M in order to cover the perforations M in thecylinder C, so as to give the moisture absorbed by the cotton wrapper Mfrom the wet surface of the cold-pressing cylinder, a chance to bewithdrawn, together with the air, by the suction pump just referred to.The packing nut N screwed upon the sleeve 0 screwed to the end of thejournal P makes an airtight joint between the interior of the head C andthe e suction. pipe D, and the union J makes an airtight joint betweenthe U-piece G and the elbow-piece K, held by the bracket 5/.

While the suction cylinder C will remove the moisture formed upon theoutside of the cold-pressing cylinder A more thoroughly when driven asjust described, I can, particularly on light-weight goods, dispense withthis gearing, and let the cylinder C simply revolve and be driven onlyby contact with the cold-pressing cylinder.

As to which in ethodthe positively driven, or the frietioi'iallydrivenis preferable is best determined by the amount of moisturecontainer] in the fabric that is to be coldpressed. A fabric loaded withmoisture before cold-pressing, will deposit very much more condensationupon the outside of the cold-pressing cylinder than the same fabric willdo when fairly dry. Also, a lightweight fabric, even if givenconsiderable moisture before cold-pressing, is less apt to wet thecold-cylinder as much as a heavyweight cloth given about the same degreeof moisture before cold-pressing, because the heavy-weight will hold andretain more of it. Therefore, I build my machine with the gear-driveshown, when excessive moisture is made, and leave it off on ordinarywork, where the cloth is loaded with less moisture before cold-pressingand gives off less condensation to the chilled cylinder when contactingtherewith.

In the practice of my invention, it is desirable, when stopping themachine, to raise the cylinder C from the position it occupied duringcold-pressing, as shown in Fig. 6, to that shown in Fig. 7 so that theabsorbent cotton wrapper M which becomes damp, and more or less wetduring cold-pressing, will not remain in contact with the cylinder Awhen the latter stands idle.

Although Figs. 6 and 7 show only one end of the machine it will beunderstood that what is said of this end, applies in the main to theopposite end, and a repetition of the drawings appears thereforesuperfluous.

Referring to Figs. 6 and 7, 71 is a bracket, fastened to the end of theswing-arm h, a. duplicate of this bracket being also fastened to the endof the swing-arm 72,, at the opposite end of the machine, and a flat bar7L extending across the machine is made fast to both to unite them.Behind the bar 71 is fastened a link a, one near each end of themachine, to which is hooked a hook 711., at the end of a chain 0, whichruns over the sheaves 7) and (j in posts Q. The other end of the chain 0is secured to a sheave r fast upon the shaft 8 revolving in brackets 2"at the back of the post Q, one of which post... as already statedisfastened on top of the frames B at each end of the machine.

At the end of the shaft .5 extending beyond the post Q. is keyed a gear6 meshing with apinion a running on a stud to secured to a bracket 2 andfixed to this pinion at is a hand-wheel o by turning'which the shaft 8can be caused to wind upon the sheave r, a part of chain 0, or to unwindit therefrom; the shaft 3 carrying next to the frame B between it andthe gear 6 a ratchet wheel a, with which cooperates a dog on swingingupon a stud 'w, screwed into the frame B, in order to lock the ratchetshaft 3 in any position desired; for instance,that shown in Fig. 7.Thus, the cylinder C may be raised out of or lowered into contact withthe cold-pressing cylinder A whenever desired. 1 v V In my machine,patented August 4th, 1896, Number 565,072, the apron used is made offelt, which to a certain extent is elastic and yielding, and enough so,to allow dress-goods or light-weight fabrics to pass through the'machinein a continuous manner that is to say, with the ends of the pieces sewedtogether in order to make of them one continuous web of cloth, theimpressions made by passing seams in the felt apron not beingsufiiciently deep to mark the goods so as to render them objectionable.Hence, generally, a leader is sewed on to the .last piece of goods, asis customarily done when running an ordinary rotary press with no apron,and this leader is left in the machine after the days work is over, tosew onto it the following morning the first piece of another continuousweb of cloth, consisting of many pieces of cloth sewed together endwise,like above mentioned. This is done, to do away with introducing eachpiece of cloth singly, which, as the machine is now constructed, wouldcause quite a delay of time, because it being intended for continuoususe, no special pro-vision is made to render the introduction of thecloth into the mouth of the machine particularly easy.

In my present invention I prefer to use a cotton apron in place of thefelt apron, as used in hot-pressing heretofore, because, to get thedesired effect, I have to impart a harder pressing to the goods. Andwith the harder pressing, the goods cannot be sewed together any more ina continuous web, because the seams would damage my cotton apron, whichis tin-elastic, and less thick than the felt aprons. Hence, whencold-pressing with a cotton apron, I have to introduce each piecesingly, to avoid cutting the aprons, which a seam might do under severepressure.

Referring to the drawings, the apron R after passin over' the draft-rollA", oes

down around idler rolls S and T, and com ing up in front of the machine,goes over the front roller V to the coldcylinder A. The front roller V(see Figs. 9 and 10) runs in swing-pads W, which turn on pivots or studsW and have toothed segments or circular racks W, into which mesh pinionsX keyed upon shaft Z, which extends across the front of the machine andrevolves in brackets 14 fastened to the frame B.

On one end of the shaft Z is fastened a hand-wheel Y which has a coupleof holes 1 and 2 drilled into the side of its rim. These holes 1 and 2register with a catch pin 3 in order to hold the hand-wheel fast in thetwo positions shown in Figs. 9 and 10, the catchpin moving in a holedrilled into an arm projecting out from the bracket Z.

'By this means when the hand-wheel Y is turned to throw the apron roll Vbackward, as shown in Fig. 10, an open mouth or triangular pouch t isformed bet-ween the cyl inder A and the'apron R in its passage from theroll V toward the cold-cylinder into which mouth I the end of a piece ofcloth can conveniently be placed by the. operator, and smoothedout byhim to make sure of a proper start. When, after placing the smooth endof the cloth into this mouth, or pocket 4, the roll V is thrown forwardagain, as in Fig. 9, and the apron will hold the cloth against thecylinder, so that when the machine is started and cylinder A and apronIt move forward together, the cloth will be held flat and smoothlybetween the.
